Cinnamon challenge

Last year the "Cinnamon Challenge" went viral with over 50,000 videos on YouTube depicting coughing teens trying to eat a spoonful of the spice. But the stunt can be dangerous, especially if cinnamon is inhaled.

A new study in the Journal of Pediatrics reports dozens of teens needed emergency care in 2012 after attempting the "Cinnamon Challenge," arriving at the ER with trouble breathing or having choked on cinnamon. Some had to be hospitalized for collapsed lungs. There were also nearly 200 calls to Poison Control related to the challenge.

While the fad is fading, researchers say there are still videos of teens taking part in this trend. Doctors and parents need to help inform them of the dangers of taking on this challenge.
